TABLE AND LATHE FOR Application led September To all whom t may co/noem: f

Be it known that I. EMonY E. BUrTER- FIELD, a citizen of .the `United States, residing vat Lewistown, in the county of Fulton and State of- Illinois, have invented certain new and useful ,Improvements in a Table and Lathe for Motor-Vehicle Engines, of which the following is a specification.

My invention relates to a table and lathe for motor vehicle engines, 'and it is specially ladapted for use in automobile repair' shops hold the engine in a rigid manner, in either upright or inverted position, and at any desired height. Thepartsby means of which the engine is secured in'place are also oapable of. adjustment to adaptthe same to motors of various sizes and shapes.

Other features and advantages of the invention will more fully appear from the following specification. reference being had to the accompanying drawings. in which:

tion` Fig. l-shows the invention in side elevai with some of the. parts shown in section.

Fig. 2 is a-'fragmentary plan view of the table 2.

Fig. 3 is an end -view thereof.

Fig. 4 is a detailof the gear-wheels 23 and 24. disengaged.

Fig. 5 is an outer ley 11.

1 represents a base of rectangular form. upon'which is supported a table 2, b v means of triangular frames 3, the lower inclined edges of which rest upon similarly formed tracks at the ends of the base, while the upper inclined edges of such frames engage similar edges on the lower side of the table 2, Overlapping anges 4 on said table hold the same from lateral movement on the frames. and .said frames .are in turn held from side `play by Hanges 5 `on the base 1.

At their inner ends the frames 3 are provided with cross-bars 6, fitted centrally with end view of the pul- 1,524,855 PATENT OFFICE.

threaded openings to receive similarly threaded ends of a rod 7, at a central point of which is a. hand-wheel 8, by means of vwhich said rod can be rotated. The threads on the ends of the rod are oppositely disposed, so that the rotation of such rod operates to move the frames 3 toward or from each other, as desired. This results in acorresponding raising or lowering of the table 2. Endwise movement of the rod 7 is prevented by means of a. frame 1a, supported from the base 1 the arms of which bear against the faces of the wheely 8.

Rigidly attached to one end of the base 1 is a hollow support 9, vin the upper part of which is journaled one end of a shaft 10, the other end of said shaft. being supported in a bearing in a bracket 9a secured to the support 9. Mounted on the shaft 10. so as to r0- tate freely thereon, is a pulley 11. to which movement may be imparted by belting in the usual manner. On the outer sideof said pulley is a web 12, in the outer flange of which are held shoes 18, engaged by the outer ends of pins 14, which have a pivotal connection with a clutch sleeve 15, slidable on the shaft 10 and rotatable therewith. The clutch sleeve is fitted with a. elutchlever 16 by means of which it can be moved inwardly on the shaft. forcing the shoes 13 into engagement with the rim of the pulley 11. and imparting the movement, thereof .to the shaft 10. rThe pins 14 also have a threaded connection with the sleeve 15, so that by rotating the same the shoes 13 can be varied in position with relation to the rim of the pulley.

On the opposite side of the pulley 11 from the web 12 is a similar web 17. connected with the end of a. sleeve 18, loosely mounted on the shaft 10. In the outer flange of the web 17 are shoes 19. engaged by pins 20, pivotally connected with a clutch sleeve 21 slidablefon the sleeve 18. and rotatable therewith. Said sleeve can be operated by means of a clutch-lever 22. On the inner end of the sleeve 18 is a. gear-wheel 23, in mesh with a gear-wheel 24. of larger diameter on a sleeve 25. adapted to turn loosely upon a shaft 26. rotatable bearings 27 in the housing 9. To the opposite end of the sleeve 25 is fixed a gear-wheel 28, adapted for engagement with a gear-wheel 29 of larger diameter, fixed on the shaft 10. By operation of the sleeve 21 the shoes 19,-are forced outwardly into engagement with the pulley 11,

'as shown '1. By this inea-ns the'movement of such pulley can be imparted through the gear-train 23*24-2829 at a greatly reduced rate of speed.

The shaft 2G has a central enlarged portion 30, eccentricaily-'d-isposed, and by turning such portion of the shaft downwardly. as shown in Fig. 4, the wheel 24 is moved away from the wheel 23, and the wheels 28 and 2,9 are similarly separated. The sha-ft 10 is then free to rot-ate without interference .fromsaidgearing. The shaft i26 maybe inverted by means of a handle 31, having a lug32 for engagement with a. notch in the end of the bearing 27, whereby such sha-ft may vbe held from movement when the wheels are in mesh.

It is obvious that whenever either of the Vclutches 13 or 19 is in engagement with the pulley 1l, the other one of said clutches must be out of engagement therewith. Nothingis claimed broadly herein on such clutch arrangement, as any suitable clutch devices couldbe, substituted therefor.

On the innerend of the sha-ft 10, is a, 'head 33, having a. central angular opening to receive the similarly formed end of a 7motor crank-shaft. Such head can .also be fitted with chuck devices, if desired, for engagement with the endof' a shaftwhich it is intended to have rotated from the ,shaft 10.

When the table 2 has been adjusted at any desired height it can be held in place `by means of bolts 34, passing through projections 35 on said table and slots 36 in one side of the support 9. Said table has a cenv vtra-l opening'37, at the sides of which are secured standards38, by means of feet 39,

which have a pivotal connection with theV table by means of bolts 40 passing through the ends of said feet and held in channels 42 in the table top, at the sides thereof. The standards 38 are threaded and provided with clamps 42, adapted to embrace the standards tightly and hold such clamps in adjusted positions thereon. Lock-nuts are also providedon said standards beneath theA clamps tohold the same against. downward pressure. The clamps 42 are fitted in one 'of their ends with maybebronght to bear againstparts of an engine `which is supported on the table 2, to hold `the same in place. Engineswhich have a four point support would be held in place vby two pairs of the clamping devices, but for those having a three-point supportone pair l,woldmbe used at the sides, and at the end an additional standard 44, having aA foot 45, in which is lfixed al 'bolt 46, held in a channel l47 centrally of the table, at the outer end of the'opening 37. The standard I44 is Fitted with a clamp 48, similar to the clamps 42. Only the larger class of engines .with a removable headcan'be secured on the table in centers. 'Y The .cla-.Inps y42 also have the frame ofthe engine. hollow bolts 43, lwhich thisavay. Infthe smaleie'typcs the.: hangers thereof are supported on the ends of the clamps 42, or on the ends of adjustment screws in the hollow bolts 43 thereof. The engine body is suspended in the opening in the table, and by adjustment of the clamps 42 and set-screwsr therein` fine vari-ations can be made in: the position of the engine, for bringing the crank-shaft thereof into alignment. with the dri-ve#shaft of .the lathe, and for other purpcxses. ',The engine can also be conveniently reached from beneath, if desired.

For the burning-in operation the motor is supported inthe table 2 in 'an inverted position, andy the table raised or lowered until the shaft 10 lis inline with the crankshaft of theengine, with .whichit is coupled, and theclamps'42 moved. into1 posi tion abo-ve theze'ngrine, and enga-gedtherewith. It ,will be obvious that'by'looseiiing the bolts 40 the. standards 38,arencap'able of adjustment longitudinally of the table 2i and also in a circular ,field with Vsaid bolts as a swing- 4ing.adjustinent uponv the standards, and by these various adjnstmentsfit ispossible to Abring the clamps intouany desired'positionl 4with lrel-ation tothe wonk'on the table.

At the start of the burning-.in operation the v.bearingsnare.likely vto be tight, and it is desirable to 'turn the .crank-shaft more slowly and with a greaterr amountof power,.

than ,after they'become wprn alittle.. This is accomplished by .means of the indirect transmission of the power through thetra-in of gearing heinbefom decreed.. ,After the .bearings becomej worn more the shaft 10 is driven directly from the pulley l1. at the increased rate vof speed. I l' For. theworking yout operation,v and, other work to be perfrmed upon a.,motor, such motor v is held on the table in its natural position, and it can' be supported directly ,onh the table, or upon the ends of the clamps 42.' Where it is 'desired todo'so` ,inx lace of using the hollow boltsl43, common. olts may` b e employed, passingdthrough thef hollow bolts and into convenient openings in A rigid connection can thus be secured between the` engine and clamp arms.l y

When the.motor `is in aninverted posif tion on the table 2'the pistons 'of such motor can .be removed downwardly, tln'ough. the opening 37 in theA table, and returned to position therethrough. :This obviates the necessity of .removingthe crank-shaft, as frequently has to be done beforethe ,pistons can be taken out. Neither isi't necessary to -.remove the transmission.devices in ord'er to drive the crank-shaftfrom the shaft 10, as the engine can be. placedl on the table with Veither endl towards theshaft 10, and such shaft coupled directly with the crank-shaft or with the universal coupling 'at the end of the transmission devices.

At the outer end of the table 2 is supported an arm 49, by means of a bolt 49a held in the channel 47, the arm being formed into a 'fork 50, on the ends of which are bearings 51, for the support of the rear axle of an automobile, the drive-shaft of the car eX- tending above the table 2 and being connected with the end of the shaft 10. By rotation of such drive-shaft the action of the differential can be observed and corrected, if necessary. By movement of the bolt 49a in the channel 47 the Jr'ork 50 can be adjusted with relation to the end of t-he shaft 10.

It will be seen that with a table of suitable height, an engine or other parts supported thereon will be easy of access. By reason of the engine being held in place by devices at the sides thereof` parts of the engine, such as the engine block", crank-shaft, and other parts can be easily removed and replaced, there being no interfering crossbars'o-r other devices that have to be removed or replaced in taking out the engine parts.

The invention has been shown and described herein as being specially designed for use in connection with the engines of motor vehicles, but it is not limited to such use, as various applications and adaptations thereof can be made in connection with other uses, Without departing from the spirit thereof.

What I claim and desire to secure, is:

A device of the class described, comprising a base, a table supported thereon so as to be vertically adjustable, provided with two or more channels longitudinally thereof and having a central opening adapted to receive an automobile engine; fastening devices adjustable in said channels; threaded posts having an eccentric connection with said fastening devices; clamping arms operable on said posts.l and provided with means for tightly engaging the same, to hold said arms om movement; and a drive-shaft supported at one end of said table, said clamping arms also serving as adjust-able supports for an engine supported in said opening. l i

In testimony whereof I aiiixmy signature.
